摘要
大别山区榴辉岩带中浅变质火山一碎屑岩层组合，及其中相当于震旦晚期孢粉组合的发现，为确定大别山区表壳岩的时代，及其与邻区的地层对比提供了重要依据；通过对区内标志岩层组合的系统追索，所确定的构造变形特征，对正确认识该造山带的形成演化具有重要地质意义。
The discovery of meso-and epi-metamorphic volcanic-clastic rock bed association and itssporopollen association of about the late Sinian in eclogites provides a basis of importance for determing thetime for surfacial crust rocks in the Dabie Mt.and their correlation with the neighbouring area of strata. Thedetermined structural deformation features through systematic tracing the marker bed in the area are geologi-cally significant to correctly recognizing the formation and evolution of the orogen.
